REFRIGERATOR-TANK.

IQN fanning part. of Letters Patent No. 3 l-6,529,datcd August 3, 1886.

Application filed June 7, 1886. Serial No. 201,317. (X0 model.)

(To all whom, it may concern.-

Be it known that l, TASI'IINGTONA. H. Bo- GARDUS, 2d, a citizen of theUnited States, rcsiding at Newark, in the county of Essex and State ofNew Jersey, have invented certain new and useful Improvements inRefrigerator- Tanks; and I do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

My invention relates to certain new and useful improvements inrefrigerator-tanks; and it consists in the various-shaped metallicdevices and their attachment to said refrigeratortanks whereby saidtanks are strengthened and the conducting and cooling surface increased.

Heretofore refrigerator tanks havebeen constructed with comparativelyplain surfaces, the warm air of the chamber or car coming in contactwith said smooth sides or surfaces cooled and descended slowly, and thegreat body of warm air in the car or room in which said tanks werelocated was gradually reduced in temperature, and rarely reached andmaintained that low degree of temperature desired, which with myinvention is quickly secured and held.

The objects of my invention being to cool the air rapidly in a room orcar in which refrigerator-tanks are placed, and, further, to maintainthe desired temperature during the transit ofsaid car, or to keep thedesired temperature in a room or vessel to any required limit of time,and, further, to materially strengthen said tanks from breakage by undueexpansion, or from vibration by sudden jar or jolt, I attain theseobjects by means of the peculiar construction and arrangement of thevarious parts of my invention, which will be more fully pointed out anddescribed in the specification and claims, reference being had to thedrawings accompanying this application, and forming part of the same, inwhich Figure l is a perspective view of my invention showing the tankwith metal strips secured. Figs. 2, 3, at, 5, G, 7, S, and 9 are detailplan views showing the different forms of construction of theattachments.

Similarletters refer to similar parts throughout the drawings.

Referring to the drawings, A represents a series of tanks of anysuitable form and size, and constructed of material adapted to thepurpose, into said tanks ice or other cooling material being placed forthe purpose of reducing the temperature ofthe surrounding air. On theouter surface of said tanks A a series of projecting plates, 13, aresecured by means of screw-bolts, rivets, nails, lip-flange, and welt, orany other suitable means whereby said plates may be held rigidly to theouter face of said tanks, the purpose of attachment of said plates tothe tanks being that their surfaces, projecting out from the sides ofthe tanks into the warm air surrounding said tanks, rapidly cools theair, which by contraction rapidly falls to the bottom of the floor ofthe car or room,whereby a current of ai r is produced, and the car orroom rapidly filled with cool dry air of the temperature desired, whichmay be indefinitely sustained.

Figures of illustration 011 Sheet 2 show the different forms ofattachments, Fig. 4 being a plate with perforations a, for attachment tothe tank A, and provided with right-angle projection a. Fig. 5 shows aplate with perforations Z), for similar attachment, and a central ribprojection, Z). Fig. 6 shows a plate with perforations c, and projectingplate 0, with a corrugated edge. Fig. 7 shows a plain plate adapted tobe attached by any suitable means, and Fig. 8 being formed withprojecting lugs f, and attached in similar form, Fig. 9 being a platewith perforations d, and two project ing flanges, (1, formed at rightangles with their base, and F1 g. 10 shows a \/-shaped plate, 71, withprojections, h, Fig. 2 being formed V-shaped, or with a sharp projectingedge, 9, the base being secured to the tank by any suitable means, Fig.8 showing lip-base with perforations c, and a central projecting rib, c,all of said plates herein described being formed of metal, either bybeing rolled, hammered, stamped up, or cast, as the manner ofconstruction not being essential, the forms and their use being theessential feature of my in vention. In securin g said plates to saidtanks, in some cases they are secured vertically, and

in others horizontally and obliquely, as may I 5. A refrigerator-tankprovided with inbest suit the purpose.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, :is

1. Atank attachment for cooling purposes, consisting of metal projectingplates secured to the outer surfaces of refrigerating-tanks,

- substantially as and for the purposes set forth.

2. A refrigerator-tank consisting of a tank with outward metalprojections adapted to contact with the surrounding air, whereby thetemperature of said air may be reduced, substantially as and for thepurpose set forth.

3. The method of cooling airwithout adding moisture by attachingmetallic projections to one or more refrigerator-tanks, substantially asand for the purpose set forth.

4. A system ofcooling and drying air within an inclosure, consisting ofa series of ice-tanks provided with metallicprojections across theirouter faces, said projections connecting said tanks, substantially asshown.

clined metallic projections on its outer surface, 2 5 whereby the cooledair, by contact with said projections, is rapidly deflected to the baseof said tank, substantially as and for the purpose, set forth.

6. Metallic plates for the outer surface of 0 refrigerator-tanks,consisting of plates provided with projecting flanges or corrugations,with suitable means for attachment, substantially as set forth.

7. A refrigerator-tank having ice within 5 and provided on its outersurface with inclined metallic projections secured by lip-flanges,substantially as set forth.

In testimony whereofI affix my signature in presence of two witnesses.
